Mesh Process Node

Overview

The Mesh Process Node processes an input polygon mesh and generates a point cloud that can be used for finding model features.

  • Model Mesh

    A polygon mesh for the model (.ply). Usually from Reader.

Process Settings

  • Process Type (Default: Generate Cloud)
    The type of mesh processing performed. Select from one of “Generate Cloud” or “Generate Edge”.
    • Generate Cloud: Generates a dense cloud of the mesh’s surface.

    • Generate Edge: Generates a point cloud with the mesh’s edges. Recommended for flat objects.


Procedure to Use

  1. Insert a Reader, and a Mesh Process node.
    ../../_images/mesh_process_procedure_1.png
  2. In the Reader node, read a mesh file. Here is a mesh file if you need one.

Exercise

You are given this mesh object, which looks like this:

What Process Type is better for this particular object?
















Answers for Exercise

Since the object is very flat, the “Generate Edge” process type is the better option.
